Reply to Bragnouf, GregK and Dboltenko regarding bladder repairs...
It is not that hard to heat-weld repair your kite bladders yourself.
I have had success on all attempts.
You need a bit of patience and common sense to figure out what to do in which order....
You need a normal household Iron, some baking/oven paper, a pencil or other small strip of wood and a kitchen towel..
Put the pencil at the bottom, the two layers of bladder material you want to weld on top of it, oven paper on top. Use towel to protect the part of bladder you do not want to weld from the heat. Put your iron on the right temp setting (no steam) and apply pressure to the pencil...
You find the right temperature by doing a test on a piece of bladder material. (tip of strutt usually has excess material). The required time is usually around 5 to 10 sec.
Too hot and you will get bubbles and burned material or material totally melted.. When it cools down it will be to hard an brittle. To cold and it doesn't stick.
usually bladders are too big (long and too large diameter) for the strut or LE so you have a bit of room of play for repairs.
I am sure you will be able to find more detailed instructions elsewhere (YouTube) if you search well.
So you can choose: These repairs cost time... or money...
